Abstract
The utility model relates to a reverse osmosis system which comprises a raw water tank, a membrane element assembly and a pure water outlet which are sequentially connected, wherein an electric heating device is arranged between the raw water tank and the membrane element assembly, a temperature detection device is arranged between the membrane element assembly and the pure water outlet, the electric heating device is connected with the temperature detection device through a PLC (Programmable Logic Controller) control unit, a thick water outlet of the membrane element assembly has two branches, one branch is connected with the raw water tank, and a return valve is arranged on the branch, which is connected with the raw water tank, of the thick water outlet. The reverse osmosis system is simple in structure and stable to work; and the work efficiency of the reverse osmosis system can be effectively improved.
Description
Technical field
The utility model relates to the technical field of water treatment facilities, especially a kind of counter-infiltration system.
Background technology
In the technique known field, counter-infiltration system is mainly by carrying out reverse-osmosis treated by the membrane component assembly to former water, and the efficient of membrane component in the process of work is closely bound up with the temperature of former water, and is low excessively as if former coolant-temperature gage, reverse-osmosis treated efficient also can decrease, and has increased production cost; If former coolant-temperature gage is too high, then can reduce the service life of membrane component internal structure, so both needed former water is carried out to a certain degree intensification, can make temperature be no more than certain scope to avoid damaging membrane component again.
The traditional water treatment process is that dense water all is back to raw water box, has avoided the discharging waste of dense water like this, but because dense water ph value is higher, has generally reached 9-10, and the reuse of this water influences to some extent to former water ph value, influences the reverse-osmosis treated effect.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the problem that proposes in the above-mentioned background technology, the utility model provides a kind of counter-infiltration system, and it is simple in structure, and working stability can effectively improve the operating efficiency of counter-infiltration system.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of counter-infiltration system, it comprises raw water box, membrane component assembly and the pure water outlet that connects in turn, be provided with electric heater unit between raw water box and the membrane component assembly, be provided with temperature-detecting device between membrane component assembly and the pure water outlet, electric heater unit is connected with temperature-detecting device by the PLC control module; The dense water out of membrane component assembly has two shunt, and wherein a shunt links to each other with raw water box, and the shunt that dense water out links to each other with raw water box is provided with return valve.
The beneficial effects of the utility model: counter-infiltration system of the present utility model is controlled electric heater unit by the PLC control module, the PLC control module is gathered the detected temperatures from temperature-detecting device, if the PLC control module in time stops the work of electric heater unit when temperature is too high; If temperature is crossed when low the PLC control module and is in time opened electric heater unit.Dense moisture is two shunt, a part of concentrate recirculation wherein is to raw water box, and this part refluxes and can reduce former water salt content after mixing, simultaneously owing to the dense water yield that refluxes reduces, the dense water of high pH value is significantly reduced the influence of former water ph value, can avoid because of the influence of pH value increase to system.This programme is simple in structure, and working stability can effectively improve the operating efficiency of counter-infiltration system.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1. raw water box, 2. membrane component assembly, 3. electric heater unit, 4. temperature-detecting device, 5.PLC control module, 6. return valve.
The specific embodiment
The utility model counter-infiltration system as shown in Figure 1, comprise the raw water box 1, membrane component assembly 2 and the pure water outlet that connect in turn, be provided with electric heater unit 3 between raw water box 1 and the membrane component assembly 2, be provided with temperature-detecting device 4 between membrane component assembly 2 and the pure water outlet, electric heater unit 3 is connected with temperature-detecting device 4 by PLC control module 5.Control electric heater unit 3 by PLC control module 5, PLC control module 5 is gathered the detected temperatures from temperature-detecting device 4, if PLC control module 5 in time stops the work of electric heater unit 3 when temperature is too high; If temperature is crossed the PLC control module 5 timely electric heater units 3 of opening when hanging down.
Wherein the dense water out of membrane component assembly 2 has two shunt, and wherein a shunt links to each other with raw water box 1, and the shunt that dense water out links to each other with raw water box 1 is provided with return valve 6.This part refluxes and can reduce the salt content of former water in the raw water box 1 after raw water box 1 mixing, because the dense water yield that refluxes reduces, the dense water of high pH value is significantly reduced to the influence of former water ph value simultaneously, can avoid because of the influence of pH value increase to system.
